The following is a detailed description of the using process of the gas sampling device provided by the embodiment of the present invention with reference to fig. 6:
use the embodiment of the utility model provides a during gaseous sampling device, can take off sampling bottle cover 4 from sampling bottle 3 earlier, later take off sampling bottle lid 1 from sampling bottle 3. After the sampling bottle cap 1 is removed from the sampling bottle body 3, a liquid, which may be water, is injected into the sampling bottle body 3. The sampling bottle cap 1 is then placed on the sampling bottle body 3. When the sampling bottle cap 1 is covered on the sampling bottle body 3, the sampling bottle built-in pipe 2 is positioned in the sampling bottle body 3.

When it is then desired to use the gas sampling apparatus to collect gas from the well, the gas inlet nipple cap 14 is removed from the gas inlet nipple 12 and the gas inlet nipple 12 is connected to a gas release valve on the casing of the well. After which the air-conditioning mouthpiece 13 is opened. After the air adjusting nozzle cap 13 is opened, the air inlet nozzle 12 is connected with the air release valve, the air adjusting nozzle 11 is not communicated with the air inlet nozzle 12, and the water in the space between the outside of the sampling bottle built-in pipe 2 and the sampling bottle body 3 still keeps a pressurized state. The gas release valve is then opened and gas from the well flows through the gas release valve into the gas inlet nipple 12 and drives the flow of water in the space between the outside of the sample bottle insert tube 2 and the sample bottle body 3. When water in the space between the outside of the sampling bottle internal pipe 2 and the sampling bottle body 3 flows to the scale marks on the sampling bottle body 3, the volume of the gas entering the sampling bottle body 3 can be determined according to the scale marks. When the gas in the sampling bottle body 3 reaches the gas volume to be collected, the gas inlet valve is disconnected with the air release valve. And covers the gas inlet nozzle cap 14 and the air-conditioning nozzle cap 13 on the gas inlet nozzle 12 and the air-conditioning nozzle 11, respectively. Finally, the sampling bottle cover 4 is covered on the sampling bottle body 3.

And injecting air with pressure into the sampling bottle built-in pipe through the first through hole. The air with pressure can exert pressure in the liquid in the sampling built-in pipe, the liquid in the sampling bottle built-in pipe can flow to the outside of the sampling bottle built-in pipe after being pressurized, and the liquid outside the sampling built-in pipe is driven to move to the bottle opening of the sampling bottle body. When the liquid in the sampling bottle body flows to the second through hole, the second through hole is plugged, and the first through hole is plugged.
Then the second through hole is opened and connected with a deflation valve on the casing of the oil well, then the first through hole is opened, and then the deflation valve is opened. The gas in the oil well can flow to the second through hole through the deflation valve and flow into the sampling bottle body through the second through hole, so that the gas sampling device collects the gas in the oil well. That is, at the in-process of sampling, need not to prepare the extra container of dress water to, the sampling bottle lid can be with the bottleneck sealing connection of sampling bottle, and the bottle lid is difficult for droing from the sampling bottle, makes the gas of gathering be in gas sampling device always, thereby has improved sampling efficiency.
